To remove the crankshaft pulley on an Opel Astra Ecotec, first, ensure the engine is cool and disconnect the battery. Use a socket to remove the bolt securing the pulley, but you may need to hold the crankshaft in place with a crankshaft holding tool or a flywheel lock. Once the bolt is removed, gently pull the pulley off the crankshaft. If it's stuck, using a harmonic balancer puller can help safely extract it without damage.
You remove no pulleys. Just loosen the belt and then remove the alternator.
In a 1.7 diesel Vauxhall Astra, the crankshaft position sensor is typically located near the bottom of the engine, mounted to the engine block or the transmission bell housing. It is often positioned close to the crankshaft pulley or flywheel. To access it, you may need to remove some components for better visibility and reach. Always refer to the vehicle's service manual for specific details and diagrams.
On the Astra G (1998-2003) it is under a cover in the center console under the emergency brake handle.

I assume by 1342 you mean the firing order of the cylinders. By convention, cylinder number one is always at the crankshaft pulley end of the engine, so on the Astra, if you are stood with the bonnet open looking at the engine, cylinder 1 is on your left. Admittedly it does get a bit more complicated with "V" engines, but that does not apply to the Astra.

To pour gear oil into the gearbox of an Opel Astra 180 with an Ecotec engine, first ensure the vehicle is on a level surface and securely lifted if needed. Locate the gearbox fill plug, typically found on the side of the transmission. Remove the fill plug using the appropriate tool, then use a funnel or pump to pour the gear oil into the fill hole until it reaches the recommended level. Replace the fill plug securely after pouring.
the cam timing mark is behind the belt front cover,take it off and you will see the mark on the drive cog,the alignement mark is on the back cover at the top. the other timing mark(crank shaft)is behind the pulley,there are no marks on pulley. to align them properly you need to remove the bottom pulley (crankshaft),remove the timing belt cover and timing belt,then align each pulley to their marks,refit bottom pulley and timing belt and check that marks are still aligned on respective positions. if they have moved,take belt off top pulley,aligne marks,refit belt,check again for mis-alignement.one tooth out is allowable on one pulley if o/k refit front cover,start her up.
